    CPU and System Topology

    Server Description

    A memory-optimized virtual server featuring dedicated AMD EPYC processors, high RAM density, and local SSD storage for database workloads.

    Microsoft Azure E16a_v4 is a memory-optimized virtual machine from the EAv4 family, powered by an AMD EPYC 7452 processor. It features 16 dedicated vCPUs, 128.0 GB of RAM, and 410 GB of local SSD storage. Operating under Microsoft Hyper-V, this x86_64 server delivers average multi-core CPU performance, memory read bandwidth, and database operation speeds, though its single-core performance and uncached memory write speeds are relatively weak. With an 8:1 RAM-to-vCPU ratio, the E16a_v4 provides a cost-efficient profile for memory-intensive workloads. It is highly suitable for database hosting, caching layers, and general-purpose memory-heavy enterprise applications.

    Workload Profiles

    0.7Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
